Diesel fuel derived from vegetable oils: Preparation and use of rape oil methyl ester

Abstract Austria's own supply of vegetable oils and protein feedstuff is discussed. Vegetable oils can also be used as diesel fuel in farming machinery and may therefore ensure continued cultivation during an energy crisis. As there are problems connected with the utilization of pure vegetable oils in engines, an inexpensive and simple method for the transformation of large quantities of rape oil into its methyl ester is outlined. The specifications of this improved fuel are given and the results of a long-term engine test are discussed. Special attention is given to the formation of deposits and the dilution of lubrication oil with fuel.
